Lead AI/ML Engineer | Enterprise RAG · LLMOps · Agentic AI | 15+ Years Building Production AI Systems | Azure · LangChain · MLOps
I specialise in taking LLM and RAG systems from architecture to production, in environments where accuracy, compliance, and auditability are not optional.Over 15 years, I have worked across logistics, automotive, and enterprise technology. My most recent chapter was at DHL Group, where I led the design and delivery of three production GenAI systems deployed across multiple countries and business units. The work that best reflects what I do: → A support intelligence platform built on Azure OpenAI and RAG, integrated end-to-end with ServiceNow. It read incoming tickets, matched them against historical cases, and injected resolution recommendations automatically. Mean time to resolve dropped from 5 days to 2. → A customs document extraction pipeline that replaced a brittle rule-based system with an LLM-powered one, complete with PII detection, HITL validation, and regional compliance controls. Accuracy improved by 40%. → A knowledge chatbot that made internal documentation actually searchable, pulling from 100+ Confluence pages and Jira in natural language. What sets my work apart is the bridge between technical delivery and business impact. I work closely with stakeholders to identify where AI creates real value, and I build governance frameworks that give compliance and risk teams the confidence to say yes.

Cultural Fit Analysis
The candidate has a diverse career trajectory, starting from web/mobile development and transitioning into AI/ML, indicating adaptability. The range of companies (Tesco, DHL, Tata Elxsi) suggests experience in different corporate environments. The numerous certifications, especially in Data Science and Generative AI, show a proactive approach to skill acquisition, which aligns with a culture of continuous improvement. However, the lack of detailed project descriptions makes it challenging to assess collaboration styles or specific contributions to team culture.
Soft Skills & Operational Fit
The candidate's resume lists 'Communication', 'Problem Solving', and 'Team Leadership' as skills, suggesting an awareness of key soft skills. However, without specific project descriptions or interview data, it's difficult to assess the depth and real-world application of these skills. The progression into lead roles implies some level of operational fit and ability to manage teams.
